I want them to consolidate all movement buttons into just one button. There's no reason to have all that bloat for moving left and right and forward and back when you could just have one "move to the right spot" button. Heck, if you count the diagonals that's a whopping 7 directions you can consolidate into one!
Now you might say, "but movement is an integral part of the game" to which I say, sure! Keep it! But when are you ever going to move to the wrong spot on purpose? And honestly, it should just be a toggle for those who don't want it. Personally I think not letting you move to the wrong spot just makes the game better in every conceivable way, and makes more room for other movement buttons to be added.
